Of course, but the point is that there exists energy as power, ExH,

radar wouldn't work. Anyone who says there is no energy in a
reflected wave is just pulling your leg.
But its not free. If you tap it, it won't be there to re reflect. So, I
think in the steady state you have changed the load impedance.
Moral: don't use it up, just use a negligible portion for measurement
purposes. A Bird wattmeter consumes very little actual power.
BTW, (not a
joke or sarcasm) Have you heard of Zero Point Energy? They calculate there
is something like 10**26 Joules in a cubic meter of empty space.
Yes, some people think that is the energy being measured, off and on,
in the cold fusion experiments. The question is: If one taps into
the energy being used to support the structure of space itself,
what happens to that space structure? IMO, space is the result of
the annihilation of matter and anti-matter in the early universe
and certainly still contains that annihilation energy.
